Flash point
Administrative data
Link to relevant study record(s)
- Endpoint:
- flash point of flammable liquids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2010-01-27 till 2010-01-29
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: GLP guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.9 (Flash-Point)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- ISO 2719 (Determination of flash point - Pensky-Martens closed cup method)
- Version / remarks:
- 2002
- Deviations:
- no
- Principles of method if other than guideline:
- The test portion was placed in the test cup of a Pensky-Martens apparatus and heated to give a constant temperature increase with continuous stirring. An ignition was directed through an opening in the test cup lid at regular temperature intervals with simultaneous interruption of stirring. The lowest temperature at which the application of the ignition source causes the vapor of the test portion top ignite and propagate over the surface of the liquid was recorded as the flash point at the ambient barometric pressure (988 hPa). This temperature was corrected automatically by the apparatus to standard atmospheric pressure (1013 hPa).
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- closed cup
- Flash point:
- 195.5 °C
- Atm. press.:
- 988 hPa
- Conclusions:
- ‘N-1,4-dimethylpentyl-N’-phenyl-p-phenylenediamine' exhibited a flash point of 195.5 °C according to EC Test Procedure A 9 'Flashpoint' (DIN EN ISO 2719 Procedure A) (Currenta, 2009).
- Executive summary:
‘N-1,4-dimethylpentyl-N’-phenyl-p-phenylenediamine' exhibited a flash point of 195.5 °C according to EC Test Procedure A 9 'Flashpoint' (DIN EN ISO 2719 Procedure A).
Reference
A gas flame was used as the ignition source. Ignitions were visually determined by the tester. In the first and second main tests, ignitions were determined at 194.5 °C and 196.5 °C, respectively. The mean value is 195.5 °C.
Description of key information
‘N-1,4-dimethylpentyl-N’-phenyl-p-phenylenediamine' exhibited a flash point of 195.5 °C according to EC Test Procedure A 9 'Flashpoint' (DIN EN ISO 2719 Procedure A).
Key value for chemical safety assessment
- Flash point at 101 325 Pa:
- 195.5 °C
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
